Hi, @slider2990. Thank you for reading our post an commenting on it.
There are lots of bid-based voting services bots in the steemit network running right now. And they are very similar in how they work. But some of the bots differs from others in the way they adjust their bot's settings. Besides not voting blacklisted accounts WE are proud to be the developer of the MAX ROI feature of the postpromoter bot code. That feature is now being used by several bots, including the main whale bots. Setting this parameter to 10%, for instance, means we do not give more than 10% of return to the bidder. That means no more abuse on high returns and so the bid-bots are now used to much more to promote a post then just to make a good piece of money. And that happens because half of the author's reward are paid via Steem Power (which is not as liquid as SBD). So, the bidder will never receive back, in a liquid way, the amount (SBD or STEEM) he/she have sent to the bot. And that should be the main goal of the bots: to help people to promote their posts, be known and raise new followers. So, we have being contributing to the development of the bot's code, improving the way it works to avoid abuses.
We hope to have answered your question.
